Let agents run your Sendfox audience
QX adds subscribers, organizes lists, drafts campaigns and keeps your audience clean—so you focus on creating, not wrangling contacts and CSV exports.
Stop copy-pasting subscribers, hunting through lists, and forgetting to follow up. Hand it to an agent.
A subscriber list that cleans itself
New signups get added, tagged and slotted into the right list automatically. Inactive contacts get flagged or unsubscribed—so your audience stays sharp without manual upkeep.
Campaigns drafted while you sleep
An agent pulls your latest content, drafts the campaign in your voice, picks the right list, and queues it for your approval—so sending a newsletter takes a click, not an afternoon.
Know your audience without digging
Ask plain-English questions about growth, lists and subscribers and get a real answer—with a suggested next step, like segmenting power-readers or reviving a quiet cohort.
